SPECIFICATION forming part Of Letters Patent N0. 499,170, dated June 6,1893.

Application tiled October 3l, 1892. Serial N0. 450,525. (No model.)

T0 all whom t 17e/ry concern:

Be it known that I, EMANUEL KEUsER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Racks or Frames forDyeing, which improvement is fully set forth in the followingspecilication and accompanying drawings. A v

My invention consists of a rack for dyeing ribbons and other material,the same being constructed of a frame which is provided with means -forholding the material in taut condition, and permitting the same to beexamined Without actual removal from the frame, or stoppage of thematerial in its passage through the dye, as will be hereinafter setforth.

Figure 1 represents a side elevation of a rack for dyeing embodying mylinvention. Fig. 2 represents a central longitudinal vertical sectionthereof.

Similar letters of reference indicate corresponding parts in the twofigures.

Referring to the drawings A designates the frame of the rack on theupper and lower longitudinal pieces B of which are mounted the rollersC, C', around which the material D is passed, the ends of said materialbeing secured in any suitable manner, as at E. Secured to the axes ofsaid rollers C are sprocket wheels F, around which passes the endlesssprocket chain G. On the axis of the pulley C is a pulley H, aroundwhich said chain also passes, said axis or pulley having also connectedwith it a gear wheel J, with which meshes the driving pulley K, to whichpower is imparted in any suitable manner. Pulleys L are also mounted onthe frame and bear against the chain'G for retaining the latter inproper position on the wheels F, and guiding the same in its motion.

M designates gravitating arms which are mounted on the uprights of theframe A, and carry at or near their outer ends the roller N. Mounted onthe uprights of the frame adjacent to said roller N, is a roller P,around which and said roller N, the material D is passed. Connected withthe arms are springs Q, which are also connected with the frame A, theirtendency being to assist in depressing said arms and consequentlytightening the material D passed around the several rollers.

It will be seen that when the material is properly placed on the severalrollers, and the frame placed in the dyeing vat, power is applied to thegearing, whereby motion is imparted to the sprocket chain and wheels,and consequently to the material, which latter is thus runv through thedye and subjected to the same. 4

In order to provide means for inspecting the material I employ rollersR, which are elevated or mounted on the top of the frame A, so as to beabove the dye, and the material is passed around said rollers so thatsaid material emerges from the dye in its passage around said rollers R,and is thus exposed to view. Should it be desired to liftthe material,in order to handle the same, the portion of the same on the rollers R israised,lthe arms M yielding and permitting said raising, as indicated bythe dotted lines Fig. 2. When the material is let go, the springs Qrestore the 'arms M to their normal position, thus taking up the slackof the material, and restoring the latter to its proper tension, itbeing noticed that this operation is accomplished with- 4out stoppingthe rotation of the rollers and movement of the material.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A rack for dyeing, consisting of a frame, rollers mounted on theupper and lower longitudinal pieces thereof, sprocket wheels on the axesof said rollers, a sprocket chain on said sprocket wheels, drivingmechanism connected with a gear wheel on one of said roller axis, apivoted arm with roller, and a spring connecting said arm with theframe, said parts being combined substantially as described.

2. A rack for dyeing, consisting of a frame, the rollers C mounted onthe upper and lower longitudinal pieces thereof,and havingsprocketwheels on their axes, a sprocket chain on said wheels, the pivoted armM, intermediate of said upper and lower pieces having the roller N onone end, the spring Q connecting said arm with said frame, the rollers Ron the upper part of the frame above the rollers IOO C, and the rollersL for guiding the sprocket chain, said parts being combinedsubstantinlly as described.

3. Adyeing framehaving rollers with means for operating the same mountedthereon, and additional rollers mounted on the frame above saidfirst-named rollers, in combination with a-u automatic tension deviceconsisting of i gravitating arm which is provided with a. roller, andmounted on said frame, and adapt- Io ed to stretch the Web, the severalparts being combined substantially as described.
